Operating manual
1. Intended use
JULABO circulators have been designed to control the temperature of specific fluids in a bath tank.
JULABO circulators are not suitable for direct temperature control of foods, semi-
luxury foods and tobacco, or pharmaceutical and medical products.
Direct temperature control means unprotected contact of the object with the bath
medium (bath fluid).
1.1. Description
ICC
TCF
ATC3
RS232
RS485
Pt100
PUMP
SMART
The circulators are operated via the splash-proof keypad. The implemented
microprocessor technology allows to set and to store different values that can be
indicated on the VFD COMFORT-DISPLAY and LCD DIALOG-DISPLAY. Three
menu keys facilitate adjusting setpoints, warning and safety functions and menu
functions.
The integrated programmer allows storing and running temperature and time-
dependent processes.
The control electronics including “ICC - Intelligent Cascade Control“ automatically
adapts the heat supplied to the thermal requirements of the bath.
The TCF -Temperature Control Features allow the user to have access to all
important temperature control parameters. This means: Full control on the control
mode and the chance to manually adjust or adapt control to the specific application.
Absolute Temperature Calibration (ATC3) provides high temperature stability in the
bath. With the 3-point calibration an offset is adjusted at three temperatures to
ensure an accurate temperature pattern at the selected spot in the bath over the full
temperature range.
Electrical connections:
The serial interface, switchable from RS232 to RS485, allows modern process
technology without additional interface.
Connection for Pt100 external sensor for external temperature measurement and
control.
Alarm output for external alarm message or control of JULABO refrigerating baths
or solenoid valve (cooling water).
The electronic module (option) provides 3 further analog connections (alarm input,
standby input, recorder output, programmer input).
The excess temperature protection conforming to IEC 61010-2-010 is a safety
installation independent from the control circuit. This protection can be indicated
and set on the LCD DIALOG-DISPLAY.
The early warning system for low level signals that bath fluid needs to be refilled
before the low level protection conforming to IEC 61010-2-010 causes a complete
shut-down of the main functional elements.
Intelligent pump system: The pump capacity (electronically adjustable via the motor
speed) enables to adapt to varying conditions for internal and external temperature
applications.

Operator responsibility – Safety recommendations

2. Operator responsibility – Safety recommendations
The products of JULABO ensure safe operation when installed, operated, and maintained according to
common safety regulations. This section explains the potential dangers that may arise when operating
the circulator and also specifies the most important safety precautions to preclude these dangers as far
as possible.
The operator is responsible for the qualification of the personnel operating the units.
The personnel operating the units should be regularly instructed about the dangers involved with
their job activities as well as measures to avert these dangers.
Make sure all persons tasked with operating, installing, and maintaining the unit have read and
understand the safety information and operating instructions.
When using hazardous materials or materials that could become hazardous, the circulator may be
operated only by persons who are absolutely familiar with these materials and the circulator. These
persons must be fully aware of possible risks.
If you have any questions concerning the operation of your unit or the information in this manual, please

Safety instructions for the operator:
You have received a product designed for industrial use. Nevertheless, avoid strikes to the
housing, vibrations, damage to the operating-element panel (keypad, display), and contamination.
Make sure the product is checked for proper condition regularly (depending on the conditions of
use). Regularly check (at least every 2 years) the proper condition of the mandatory, warning,
prohibition and safety labels.
Make sure that the mains power supply has low impedance to avoid any negative effects on
instruments being operated on the same mains.
This unit is designed for operation in a controlled electromagnetic environment. This means that
transmitting devices (e.g., cellular phones) should not be used in the immediate vicinity.
Magnetic radiation may affect other devices with components sensitive to magnetic fields
(e.g., monitors). We recommend maintaining a minimum distance of 1 m.
Permissible ambient temperature: max. 40 °C, min. 5 °C.
Permissible relative humidity: 50% (40 °C).
Do not store the unit in an aggressive atmosphere.
Protect the unit from contamination.
Do not expose the unit to sunlight.
Appropriate operation
Only qualified personnel is authorized to perform configuration, installation, maintenance and repairs of
the circulator.
Routine operation can also be carried out by untrained personnel who should however be instructed by
trained personnel.

Use:
The bath can be filled with flammable materials. Fire hazard!
There might be chemical dangers depending on the bath medium used.
Observe all warnings for the used materials (bath fluids) and the respective instructions (safety data
sheets).
Insufficient ventilation may result in the formation of explosive mixtures. Only use the unit in well
ventilated areas.
Only use recommended materials (bath fluids). Only use non-acid and non corroding materials.
When using hazardous materials or materials that could become hazardous, the operator must affix
the enclosed safety labels to the front of the unit so they are highly visible:
When using hazardous materials or materials that could become hazardous, the operator must affix
the enclosed safety labels (1 + 2) to the front of the unit so they are highly visible:
1
Warning label W00: Colors: yellow, black
Danger area. Attention! Observe instructions.
(operating manual, safety data sheet)
2
or
Mandatory label M018: Colors: blue, white
Carefully read the user information prior to beginning operation.
Scope: EU

Semi S1-0701 Table A1-2 #9
Carefully read the user information prior to beginning operation.
Scope: USA, NAFTA
Particular care and attention is necessary because of the wide operating range.
There are thermal dangers: Burn, scald, hot steam, hot parts and surfaces that can be touched.
Warning label W26: Colors: yellow, black
Hot surface warning.
(The label is put on by JULABO)
Observe the instructions in the manuals for instruments of a different make that you connect to the
circulator, particularly the respective safety recommendations. Also observe the pin assignment of
plugs and technical specifications of the products.

2.1. Disposal
The circulator contains a back-up battery that supplies voltage to memory chips when the unit is
switched off. Do not dispose of the battery with household waste!
Depending on battery regulations in your country, you might be obliged to give back used or defect
batteries to gathering places.
The product may be used with oil as bath fluid. These oils fully or partially consist of mineral oil or
synthetic oil. For disposal, observe the instructions in the safety data sheets.
This unit contains refrigerants, which at this time are not considered harmful to the ozone layer.
